TORPEDO.

To all whom il: may Concern.'

. Be it known that l, GEORGE ALFRED KNOX, a citizen ot' the United States. residing at 3920 Fifth street northwest, ivashington, District ot Columbia, haveI invented new and useful Improvements in Torpedoes, of which the following is a specification.

My invention relates to improvements in automobile submersible torpedoes used in offensive and defensive warfare and its objects are: The removal from the outside of the torpedo oi all trip levers, lugs, or other projections t'orstarting the controlling and the actuating mechanism. The provision of Vstarting mechanism inclosed within and attached to the torpedo aiterbody shell,'or the bulkheads therein provided, for ope 'ating the torpedo starting piston thereby admitting liask air simultaneously to the gyro spinning mechanism and to the reduc* ing-valve connected to the superheater of the turbine actuating mechanism. rThe provision of a starting mechanism carried within thetorpedo body and properly positioned therein for operative actionvt-hrough an eX- rlhe provision of a mechanism inclosed within the torpedo case, body or shellv for starting the gyroscope spinning'mechanism and the tor- ,pedo turbine driving mechanism. The provision of a device by which the gyro spinning and torpedo propelling mechanism will be started, invariably before the impulse is given which discharges the torpedo from its spoon," tube or carrier. mechanism whereby the liability ot discharging a dead torpedois -fully overcome. To simplify the starting of the gyro spinning and the torpedo propelling mechanisms. To grpatly reduce the cost ot construction ot' 'mechanism for the purpose Other objects 'and advantages of my invention will appear as the' description proceeds. Y

I attain these objects by means illustrated in the accompanying drawings, in which:

Figure 1, illustrates a transverse Section ot' a torpedo showing, in section, my improvement applied thereto. Fig. 2 is an elevation of my improvement, partly in section, looking in the direction i-ndicated by Specification of Letters Patent.

Fig. l0 is a sectional viewtaken on line X-.X of Fig. S, looking in the direction there .indicated bythe arrows. v Y ln the preferred torm shown in Figs l and Q each element is designated by its respective referencecharacter in both views and in the four modiiieations the salne reference characters are used, preceded by one hundred, two hundred.'three hundred, and four hundred respectively, to designate the correspondingl elements. n

The numerals 1 indicate parts of the torpedo case, shell or body. to the interior of which my improvement is secured by 4water tight connections in any suitable manner.

The number il designates a valve casing provided with a' packing gland 5. To the inner end of casing 4 a casing extension 6 is secured, having on its interior surface a stop 7 which limits the movementof a valve plug S when shoulder 9 on said valve plug 8 and stop 7 engage. The normal position of valve plug 8 is that wherein shoulder-9 and stop 7 are in engagement. The purpose of spring `10 is to hold valve plug S in normal position. Expansion spring l0 should bel suiiiciently powerful to Overcome the' water pressure at the depth the torpedo is intended to travel or to overcome the tor- Fig.y

In that case, extension would be constructei'l ot' sutiieient length to accommodate'- springl() which, in the construction Villustrated, is housed inside i'alVeQplug exten?v sion or cage 13..

At a suitable point on valve -asingal an extension 1:5,..liai'ing an rairpassage therethrough, is located. The air passage thr iu ,rh extension 15 vconununicates with the inside ot' valve easing -L when unohstrueted by plingn 8.

Valve basin .204 is rotatably mounted 1n bracket a al connection 241. The openings 242 :aiiiord comniunication between the inside ot valve casing 204 and cylinder 3 by way ot coiniection 241 and pipefz as shown. i` alve plug 9.08, spring 210 and cap 211 correspond lwith and perform the same vfunctions as elements 8, 10, 11 respectively in Fig. 1. 243

is the gyro settingl shaft suitably connected with valve casing 204 so that they may be rotated simultaneously.

y Nozzle 230 is adapted to bel inserted into valve casing' i104 and both rotated to any extent desired. Gyro setting shaft 243 being` non rotatably connected with valve 'casing' 204 must also rotate, thereby, through intermediatemechanisms, well known to those Skil led in the art, setting the'gyro. As the gyro-setting mechanism is not a part of my invention it is not necessary to illustrate or describe it?, l

Elements 223, 9:24, 226, 227, 22S, and 220 are identical in construction and function with elements 23, 24,' 26, 27, 2S, and 20 in Fig. 1.

In the modification shown in Figs. 5, 6 and 7 valve .casing 304 carries a rotary valve vplug 308 having two passes or ports 353 and at right angles to each other leading from a central longitudinal pass or'port 355. Either of the ports 353 or 354 may be put in alineinent with a port 350 leading to air receiver 344. lVhen it is desired to lill the 4receiver port 352-5 should be put in alinei'nent with port 350 this will locate port 354 so that it is closed b v the blank wall or. valve casing 304 and the opening through extension 315 will be closed by the blank wall of valve lug 30S and at such time air may be p'uinplel into the receiver througlra conduit i adapted to be connected with plug 308 bya screw threaded connection 349 in the bottom o't' wrench socket 2351. In filling receiver 344, air is pumped through port 352, orifices in valve cage 2348, port 355, port and port 350. lrct'Qrably. when air sufficient to operate starting pin 1),, once, is condensed in rmfeiver 544. the conduit is disconnected. iscap-e of air troni receiver 344 is prevented because the conical stop valve will be pressedinto the seat provided 'for it, by the expansion spring 347 surrounding valve stein 346, and also by the expansion of the air in receiver 344. However,`it' desired, the internal air pressure on stop valve 345 may be prevented by rotating valve plug 308 through an angle of fortyd'lve degrees. The ports and 354 being spaced ninety dcgrees apart it is obvious that a rotation of but forty-tive degrees from charging position will so locate the ports 353 and 354 that they will be closed by the blank walls ot' casing 3,04 thereby placing ports 353 and 354 out of alinenient with port 350 leading to recei ver 344, thus closing port 350 and pre# venting any back pressure against stop valve 545 by the compressed air in receiver 344.

l'Vhenever port 353 isin alinement with tion with the elements 24, 25, 26; 27, 28s

and 29 in Fig. 1.

The inodiiication vshown in Figs. 8, 9 andl 10 is designed to be operated by the flask air oi' the torpedo.

Valve plug 408 having a wrench socket 451 in its outboard end is seated in valve casing 404. 'This valve plug has two ports 469 and 47 0 communicating with each other at the center of. theplug andextendingradially therefrom at an angle of ninety degrees and so located with reference to conduit 47:2

leading' to the flask and conduit 471 inv extension 4.15 leading to pipe 2 that communication between conduits 471 and 472 may be established or interrupted by rotating valve plugl 408- through an angleof ninety degrees. p

Valve case 404 'has an extension 406 through which projects' a prolongation oi .plug 408, the protruding end of which heilig provided with teeth, forms a pinion 460 in engagement with a. rack 46.1. Upon the end of the rack 461, remote from pinion 460, a piston 462 is secured to operate in cylinder 46S. Cylinder 468 is formed in an extension ot' valve casing 404. Between the head of cylinder 468 and the free end ot piston 46:2y an expansion spring 463 is placed. E tending from cylinder 468 and communicating therewith is a. cylinder 467 in which the air tight piston 465 is located. Piston 465 carries a piston rod 464 projecting through a. stutling box toward piston 462 in cylinder 468. Between the other side' of piston 465 andv the Lead of'cylinder 467 an expansion spring 466 is placed.

By means of an end wrench inserted into socket 451 plug 408 may be rotated through 4 an angle of ninety degrees to establish comv longitudinally,

i tl ask, and

sure rises in cylinder 467 sutii'c n'umication -betweenconduits 171 and l31.72. n account of the engagement of pinion 160 and rack 461, when -pluglOS is rotated, rack -l61land its-attached piston $462 Aare moved spring 1l63being compressed thereby. -i The `A`movement ot' piston 462 is sutlicient to .carry it beyond .piston rod 461, 'thereupon spring Jf66 expands andprojects `piston rod 461 ,under pi rf'piston in its elevated position with un- .on L62 thuslocking obstructed.. connnunication between the cylinder 4:67 and pipe'2, as shownthereby operating start'nig Apin, 1. lVhen presiently to com press spring 1166 piston rod 161 is withdrawn from 'engagement with piston 462, spring 462-3 en' )ands tachcdrack`461l to normal position thereby rotating pinion +6() and its attached plug valve 408 and interrupting the flow of .air from flask VThe relief val\'einecl1ai1is1n aetly the saine as the corresponding elements in Figs. l and 2.

v rlhe operation is 'as follows: Referring.

more particularly to Figs. 1'and 2, and assuining valve plug S is in normal position. as shown at the lelt in Fig. l, the conical end ot' nozzle 30 is seated in the conical cavity in the outboard end of valve plug L8 and then thrust inwardly; plug 8, nozzle 30 and plunger valve 3l traveling together` until they reach thc point shown by nozzle 30 1, whereupon air is is to thrust plunger .valve 31 forwardly7 carrying with it valve plug 8 beyond the openinginto extension l5, uncovering openings :l in plunger valve 31 and establishing;r coinnumication between the source of'power and pipe I2; valve 2 1, is swung from the dotted lineI position to thet'ull 17 and rod 1S are driven forwardly causing starting pin 51 to operate;` {Theair passing t'ronrthe source ot` supply into the coni pressure that it may duit is under such high besluit oil' and nozzle Il() may be withdrawn almost instantly aliter the `compressed air is admitted. Springs l() and l-l expand as soon as thesupplyair is turned otl' and return valve plugSanil plunger valve 31 to their normal positions. A ir is'allowed toi-scape from the pipe, -system eontimumsly through' the small port 29 but. the loss is so slight lit does not interfere ,with the instantaneous actuation ol piston I7; furthermorefas only two lil'tiis ol a second are required to secure full headI way t'or. theJ torpedo gyro spinning mechanism, a l'ler the 'forward action ot' piston 17 is completed. and as the -l'ull launchiup movement ol the torpedo tube is ell'ccted seconds therealter` it obvious that .the loss ol air through port 2S during the time the torpedo reinalns withcylinder 3 through conduit e171,

carrying piston l-162 and its atthus 428. and 429 then acts eX- linc position,' piston v 's'i'iinning mechanism will be l ger in the tube may be safely neglected, while the torpedo is beginning its run the escape of air is continuous, quickly reducing Ithe pressure in the pipe systein'g'suliiciently to allow spring 20.t'o return' piston 17 to its normal position. Spring inthe relief systemshould` be Strong'enough to overcome a pressureof approximately Yten pounds to the square inch and spring 20'in cylinder 3 should be somewhat more powerfuhso that spring l2O will act'hefoe the leakage of air ceases and spring 25 will stop the leakage 0f air before sea water can enter.

To operate the.- modification shown in Figs, 5, 6, and 7 a suitable releasing wrench is inserted into the socket 351 and given a turn, of ninety degrees ina clock Wise di,-

rection to establish .an` unobstructed passage from receiver 3&4 to cylinder 3; piston 17 andjthe piston rod 1S are projected instantly, driving` starting pin P forwardly accomplishing the object sought. Leakage from th ivsystem goes onas in the preferred form. i

ln `the operation of the modification shown in Figs. S, 9, and 10 plug valve L108v isgiven a quarter turn in a clockwise di# rection by a wrench inserted incal socket 451. The rotation of plug valve 4 08 establishes communication `between the iask and cylinder 3 and starting pin P isoperated, but when the pressure is suflieient to compress spring 466 the air is automatically cut otl' as previously explained by the rotation 'ot'lplug valve S to its normal position, lthe leakage. of air thelrtaking place as in the preferred-form.

From the. foregoing description it wi' be seen that'I have provided an automatically operating mechanism which does away with the present crude manner of .tripping the starting hookby a long rod manually Inanipulated or by the uncertain contacting f the hook with an inwardly projecting lug, in the ,torpedo tube, after the. torpedo hasv received the` impulse which. kdischarges it and when a failure ot the two parts to cngagc results in the total loss of. a torpedo without any possibility of accomplishing the` object for which it was intended. By my mechanism the turbine. driving and gyroriably, it' there is sulicient compressed air in-'the flask to drive-them.

'lorpedoes provided with my invention do not have the usual proiectiug hook or trigwhich is sometimes inadvertently tripped.- They are. smooth bodied and can be shipped, fully charged` without providing the special devices torpedoes now requirevto prevent lnei-ldlers from tampering with them. lt is praclically an impossibility to` `operatca torpedo equipped with my invention excepting by special mechanism, designed t'or the purpose, including the nozzle sta rted, inva.-

lie

shown or an equivalent construction, and the handling of torpedoes on shipboard is thus made safe, no matter how awkward or excited the crew may be through the heat of battle'. l i
